In this context, programming environments should be simple and understandable for increasing the learning success and for easing the entry for teachers with non-informatics background. Furthermore, many robotics applications can also benefit from flexibility in the program deployment in contrast to the usual code-compile-download paradigm. To address these issues, this paper presents a flexible programming environment based on a layered robot control architecture, which involves the usage of mobile devices. Source code created on a smartphone or tablet can be downloaded to the robot controller, which organizes the programs having on-board compilation and execution environments. Besides, a versioning system adds to the comfort. The presented approach enables students to intuitively handle their robots, but can also be applied in more sophisticated scenarios where module-based flexible programming is required.","PeriodicalId":422587,"journal":{"name":"2015 International Conference on Control, Automation and Robotics","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133416826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The direct kinematic problem is addressed using both the Denavit-Hartenberg (DH) convention and the product of exponential formula, which is based on the screw theory. By comparing the results of both approaches, it turns out that they provide identical solutions for the manipulator kinematics. Furthermore, an algebraic solution of the inverse kinematics problem based on trigonometric formulas is also provided. Finally, simulation results for the kinematics model using the Matlab program based on the DH convention are presented. Since the two approaches are identical, the product of exponential formula is supposed to produce same simulation results on the robotic arm studied.","PeriodicalId":422587,"journal":{"name":"2015 International Conference on Control, Automation and Robotics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121814566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this season, the primary goal of the reservoir is impounding to get the maximum economic benefit. As people increasing concern about their environment, impact of the reservoir operation to the aquatic habitat at the downstream area becomes an increasing important factor. The conflict between economic benefit and habitat conservation makes the dispatch a multi-objective problem. In this paper, stored energy at the end of dispatch period is proposed to be the economic objective and the weighted usable area (WUA) of the habitat is used to represent the environmental demand. The multi-objective differential evolution (MODE) and a particular constraint handling strategy proposed in this paper are used to solve this problem. Simulation results show that the proposed constraint handling strategy improves the performance of MODE in solving this problem. More importantly, the Pareto optimal front of different operating condition shows that the conflict between economic benefit and environmental benefit is sharp, especially in low flow years. The degree of conflict relates to the value of average inflow. So it is necessary to consider the habitat conservation while operating. And this work provides a support to aquatic organism protection and ecological operation of the Three Gorges reservoir.","PeriodicalId":422587,"journal":{"name":"2015 International Conference on Control, Automation and Robotics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126609486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A control strategy consists of a leg stiffness controller and a foot placement controller is proposed for a biped walker. Some restrictions are considered in the control strategy, e.g. the friction and the ability of the actuator. A novel trajectory function is designed for stance phase control. The function not only can approximate the nominal trajectory with error in the order of sub-millimeter, but also can preserve the restriction on vertical velocity in spite of the horizontal velocity. To validate the control strategy and the trajectory function, simulations are implemented on a virtual ideal biped walker. The walker starts walking with a low velocity, by taking a few steps it comes to the desired walking cycle. With the proposed control strategy the walker is able to recover from a disturbance up to 20 N*m.","PeriodicalId":422587,"journal":{"name":"2015 International Conference on Control, Automation and Robotics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126062200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In practical application, d6 ≠ 0 usually occurs, hence it is required for supplemental transformation between the last frame of the D-H models and real operation frame, which decreases the efficiency. In this paper, a new inverse kinematic solution without the hypothesis of d6 =0 is proposed. We found that the joint variables of the partially decoupled robot can be separated without great difficulty even though d6 ≠ 0. The new approach uses a new multiplication sequence of the inverse matrix for solving the variables of the kinematic equation of the robot. The inverse solution process is straightforward and computationally cheap. Last, some exemplifications are given to valid the accuracy of the proposed approach.","PeriodicalId":422587,"journal":{"name":"2015 International Conference on Control, Automation and Robotics","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126369033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ultrasonic inspection on hollow axles must be conducted to ensure the safe operation of high-speed trains. The hollow axle can be artificially divided into different segment based on the shape and size of different axle segments including the transition arc section. Different inspection results from these axle segments can be obtained due to the different sound path and the different dimension of the transition arc. Simulation models about different axle segments were established by means of COMSOL Multiphysics. The difference of the simulation results, from different axle segments tested by probes with different angles and directions, are discussed, which may provide guidance for the setup of gate and selection of probes while carrying out actual ultrasonic inspection on hollow axle.","PeriodicalId":422587,"journal":{"name":"2015 International Conference on Control, Automation and Robotics","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116918451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
